5 6 COLEOPTERA 



tairuense are small in comparison with the elytra, and quite destitute 

 of punctation ; the frontal fovete, as in the allied New Zealand species, 

 are broad and deep ; the eyes only moderately prominent. The elytra 

 are elongate-oblong-ovate, rather depressed, and with rather strongly 

 impressed and closely punctured strise, the interstices being plane ; the 

 first and second striis converge at the base into a depression, the 

 outer striae do not reach the base and leave a smooth space near the 

 shoulder ; strife 2-7 become very faint near the apex. 



The species is closely allied to B. maorimim, from Christchurch, and 

 it would be difficult in a description to make their difference clear, 

 though their general aspect is very distinct ; B. maorinuin being broader, 

 more brightly aeneous ; the elytra much broader, the strife less im- 

 pressed, &c.

Differs from the section to which B. niloticiini belongs by the very 

 narrow margins to the thorax, not explanated behind, and with obtuse 

 hind angles ; the sides of the thorax are very strongly rounded, but the 

 base is much narrower than the apex ; the apical angles are not at all 

 conspicuous.

Tairua, near Auckland (Capt. Broun). 



Belongs to none of the European sections of Bcvibidiuni, but nearest 

 allied perhaps to Peryphus. The frontal furrows (broad and deep, 

 without marginal ridges) and the form of the thorax (with contracted 

 hind angles and simple fovea) are the same as in the Peryphus maorinum 

 group ; but the fifth elytral interstice has no setiferous punctures. The 

 head is small, and the eyes are not so prominent as usual in Bembidium. 

 The thorax is also small and impunctate ; it is cordate, gradually nar- 

 rowed behind until near the base, and then its sides are straight, without 

 the slightest projection of the posterior angles; which are indeed scarcely 

 rectangular; the basal fovea is narrow, and lies close to the marginal
